(57) [Summary] [PROBLEMS] To provide a polyester film for transfer foil, which is excellent in deep drawability and is useful as a base film for in-mold transfer foil. SOLUTION: Polyester (I) having ethylene terephthalate as a main repeating unit and polyester (II) having butylene terephthalate as a main repeating unit. A film made of a polyester composition in which the crystallization temperature of the polyester composition is 65 to 16 0 ° C, second-order transition temperature 40-69 ° C, and melting point 260 A polyester film for a transfer foil, which has a temperature of ℃ or less. |
